To all 'whom z't may concern l' v Be it known that I, An'rnua L. BUR'IDN, a

United States, residing at of Montana, have invented'certam'new' and useful Improve entsin Cooling-Tanks for Hardening Iceream,* of which the follow in is a specification.

y inventiqn-relates appliances for hardening ice creamafter it has been frozen in the usual manner of freezing ice creams, and its ob'ects are: first, to provideameans whereby t e cream may out the storage cans in which it is to be stored. and shipped or delivered, and, sec 0nd, to provide a means whereby the cream may be kept at a uniform of time. I attain these arrangement of parts indicated in the accompanying drawing, in which- Figure 1 is a top plan of the device with the cover removed to show the distributiop and arrangement of the several elements that make up the device, and with the receptacles set some distance apart to more plainly illustrate the circulation of the brine ammonia pipes, &c. Fig. 2' is a vertical sec.- tion of the same on the-line w m' of Fig. 3, and with the receptacles set close together as they are designed to be placed in the tank. Fig 3 is a vertical section of the same on the line w m of Fig. 2,. and Fig.

t is a sectional elevationofa receptacle with a storage can in positiorl'therein.

Similar letters refer to similar parts throughout the several vlews.

In the construction of this device I first form, a lar e tank A, having a sectional,

hinged lid so constructed that it may be opened either direction from the hinge or ivotal lines a, ines in 3. The walls and cover of this receptacle are thoroughly insulated with some-non-heat conducting substance, as indicated at a a in Figs. 1, 2 and 3, to protect the contents of the tank from the influence of theouter atmosphere, as much as possible. In this tankII place, chor several lines of receptacles, -B B,.which are designed, first, to receive and hold .the cans C while the'contents of said cans is bein hardened, and, second, to insure an equa depth of brme in the tank whether the I me e 0!

The ammonia coils, hereinbefore,

the evaporation atile refr gerant,-

scribed, are so distributed in "and throu' h the tank 'Athat a row'of receptacles B, or the cans C, may. be lacedbetween each two tiers of pipes, as in 'cated in Figs. 1, 2 and 3, -1nto which the ice cream" cans are (placed after the creamhas been frozen. in an ordinary freezer and then-transferred to these readily removed from the receptacles. with-- out first removing other, material, from between the cans and the receptacles. When the cans are pro 'erly fi placed 1n the receptacles, t e space in the tank around the receptacles and the ammoma pipesmay be filled with a strong brine that surrounds the receptacles and ammoma plpes, or the device may be used with onl alr surrounding the receptacles, and wh1le the amomnia is being forced through the pipes the air or brine in the tank is constantly agitated, either by means ofa strong being forced throughthe pi e E into the tank, or by any other availab e method, to cause the air or brine to flow in diverse strong currents among the race tacles as indicated y the j After the creamhas been properl frozen in an ordinary ice cream freezer it ouldbe placed-in this freezer and left until it lied and to the receptacles and their contents.

What I claim as new, anddesire to secure by-Letters Patent of the United States, is:

In a device of the class described, a tank having its side walls and bottom lined with eat insulating material, a supporting piece or cover at the top of the tank, havlng apertures therein, receptacles for holding ice cream secured in sald apertures and extending down into the tank, cooling coils arranged in tiers located between said receptacles, and an outer cover composed of two parts hinged together and located above said supporting piece or cover.
